Reinforced elastic body and production process thereof

Abstract

A reinforced elastic body is disclosed, which comprises a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and/or an epoxy compound and an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer. Also, a production process of the reinforced elastic body is disclosed, which comprises vulcanizing-adhering polyester fibers treated with an adhesive containing an isocyanate compound and/or an epoxy compound and then treated with an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer to a chlorosulfonated olefin compounded material.

What is claimed is: 
     
       1. A reinforced elastic body consisting essentially of a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, wherein the molar ratio of resorcin to formaldehyde is from 1:0.1 to 1:5, and the solid component weight ratio of the latex to the sum of resorcin and formaldehyde is from 1/100 to 1/1. 
     
     
       2. The reinforced elastic body of claim 1, wherein said 2,3-dichlorobutadiene-containing polymer is a 2,3-dichlorobutadiene homopolymer. 
     
     
       3. The reinforced elastic body of claim 1, wherein said chlorosulfonated polyolefin is a chlorosulfonated polyolefin obtained by chlorinating and chlorosulfonating an ethylene-α-olefin copolymer having a density of less than 0.94 g/cc. 
     
     
       4. A process of producing a reinforced elastic body comprising a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and an adhesive composed of a liquid mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, which process consists essentially of vulcanizing-adhering the chlorosulfonated polyolefin and the polyester fibers treated with an adhesive containing an isocyanate compound and then treated with an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, wherein the molar ratio of resorcin to formaldehyde is from 1:0.1 to 1:5, and the solid component weight ratio of the latex to the sum of resorcin and formaldehyde is from 1/100 to 1/1; and wherein the liquid mixture of resorcin-formaldehyde resin and polymer latex has a solid component concentration of from 2 to 50% by weight.   
     
     
       5. The production process of the reinforced elastic body of claim 4, therein said 2,3-dichlorobutadiene-containing polymer is a 2,3-dichlorobutadiene homopolymer. 
     
     
       6. The production process of the reinforced elastic body of claim 4, wherein said chlorosulfonated polyolefin is a chlorosulfonated polyolefin obtained by chlorinating and chlorosulfonating an ethylene-α-olefin copolymer having a density of less than 0.94 g/cc.
